Hi,

The following vulnerability was published for freeipa.

CVE-2024-3183[0]:
| A vulnerability was found in FreeIPA in a way when a Kerberos TGS-
| REQ is encrypted using the client’s session key. This key is
| different for each new session, which protects it from brute force
| attacks. However, the ticket it contains is encrypted using the
| target principal key directly. For user principals, this key is a
| hash of a public per-principal randomly-generated salt and the
| user’s password.    If a principal is compromised it means the
| attacker would be able to retrieve tickets encrypted to any
| principal, all of them being encrypted by their own key directly. By
| taking these tickets and salts offline, the attacker could run brute
| force attacks to find character strings able to decrypt tickets when
| combined to a principal salt (i.e. find the principal’s password).
